why does linear voltage changes on transistors base make non linear current flow ?

@Hurz Can it work stable all the time ?. Are those blue and orange power and logarithmic functions ?

what's the mathematical functions of blue and orange trace ?. I'm just trying to better understand transistor functionality.

When biasing a transistor, it can be biased into an area of linear operation, it can also be biased into a non linear area of operation. The transistors gain/input signal level can also be made large enough where it can be driven from a linear to non linear operation point.

Thats the natur of BJTs. See base emitter as a diode and bring voltage and current on a graph, and you will see current increase exponentiell to diode voltage across. Anyway, you try to learn BJTs with this circuit, start with less messy circuits and one transistor.
